Chinese experts in the field of the world's first discovery of malignant nasopharyngeal carcinoma tumor cells exist in extremely high levels of "cancer stem cells", its rate is only 5% of mass destruction has greatly incomparable. In this regard, a new treatment method will be shipped introduced. At the same time, experts said, and never suffering from a cold body of people, "scouts" more easily nap, when the tumor "under siege" when the body is also difficult to detect.
People who never cold harder to find tumors
Eat a lot of incense, good sleep, the body has never been as strong as iron wall, and never suffer from cold and other minor illnesses small pain in the crowd, once the tumor was found, often has been early, and many seem fragile, often suffer from small cold crowd, able to earlier in the incidence of early detection of abnormal body will not progress to the later stages of disease it was found out. "This shows that if we start the body's immune system eventually becoming self-regulation, it is very easy to 'nap' to fall asleep, so when an enemy attack on the human body when the scouts but did not know."
Occasionally, a cold, cold symptoms are immunocompromised and other small performance, but on the other hand it can strengthen the immune system time to awaken it for self-adjustment, sharpening and help the body restore normal immune function. And this repair, the process of adjustment to maintain the body to outside interference in a constant state of alert. Long-term without any intrusion of small disease populations, the body will have a "immune paralysis", that is a long time without having to respond more slowly to the outside world, cancer and other diseases when grown in the body, the body may be difficult to monitor the catch this signal. "This and the troops should exercise training with a token, even if it has a sophisticated weapons, eventually becoming practice, paralysis of the enemy, the other raid, even if fighting a powerful, yet reconnaissance, discovered too late."
In addition, he also cautioned that feeling good is one of the elements to prevent cancer because the mood directly affect human endocrine levels, while about endocrine levels will in turn regulate the immune system, so happy can prevent cancer is a medical reason supported. In addition, proper exercise and balanced nutrition is the recipe for the body away from the tumor.
Nasopharyngeal carcinoma first discovered cancer stem cells,
At the recent "China's biological therapy and targeted therapy cancer research will" on the Chinese Academy of Sciences, Sun Yat-Sen Cancer Hospital Yi-Xin Zeng revealed that their latest research results show: NPC does contain cancer stem cells, which is the first time confirmed that cancer stem cells in the presence of nasopharyngeal carcinoma, research results earlier this year in the global authoritative academic journal "Cancer" was published on.
The study found that recurrence and metastasis of tumor cells are not all uniform speed, "95% of the tumor cells are relatively moderate, and sensitive, through means such as radiotherapy and chemotherapy can kill, but there are 5% of the cells are very stubborn, self-replication very strong, and can produce drug-resistant capacity, such cells are called cancer stem cells. "Zeng Yi-Xin introduction, it is highly malignant and have a strong capacity for destruction of a small number of stem cells, leading to cancer treatment is often difficult to smooth, even health to deteriorate. At different stages of malignant transformation of stem cells is also a tumor cause. He explained, "If the means of radiotherapy and chemotherapy to 95% of the moderate cell killing, probably contrary to the survival of stem cells, to allow adequate space, let the further spread." For this reason, for the discovery of cancer stem cells, research into cancer prevention and control work one of the priorities.
To this end, the research team for the first time in the laboratory to isolate stem cells have the phenotypic characteristics of tumor cells, and confirmed that they do significantly better than the other tumor cells, radiation, drug resistance and metastasis. At this point, and finally the first time explicitly found that the existence of nasopharyngeal cancer stem cells. He said the view from the current study, stem cells may be related to genomic instability. Zeng Yi-Xin introduction, the second phase of the study is completed, they will start the third stage of the study, a new design, "Sequential treatment" can first kill the most sensitive to conventional treatment of tumor cells, and then against the cancer stem cells drug therapy, and strive to remove the maximum residual tumor cells. The more precise treatment have to rely on the clinical use of drugs in the future be able to guide a large number of molecular markers was found, according to the biological characteristics of the different stages of tumor-specific and choose a different administration.
